BUSHING LINER.

a plication he October 27, 1922. Serial no. 597,259.

To all whom it may concern:

Be it known that I, ABnArr N PAsMAN, a citizen of the United States, residing at Waterbu in the county of New Haven and State of onnecticut,1have invented an Improveinent in Bushing Liners, of which the following is a specification. v

This invention relates to a liner for bush ings. Heretofore in water-and other similar lines of pipin wherein plumbing tube traps are employe it has been customary to furnish a plurality of bushings with dlfiterent sized openings therein to accommodate the pipe of the diameter which might be employed in any particular case. For example, in bushings for an inch and one-half pipe it has bee-n customary to provide the same in sets with one having an opening with an inch and one-half diameter, another having an opening of an inch and three-eighths diameter, and a third, for

example, with anopening of an inch and dne-quarter diameter, so that a pipe of either til one of these diameters might be employed.

The object of my invention isto overcome this inconvenientand'expensive practice by providing a liner for a bushing of iron diameter so that in the use of the ushing without a liner a ipe of a given diameter may be employe whereas with the liner a pipe of a smaller diameter may be employed, and obviously by providing liners of difi'erent diameters pipes of as many difl'erent diameters may be employed with the bushing of a given diameter.

The linermade in accordance with my invention preferably comprises a body por-'.

tion adapted to fit within the opening in the bushing and the body portion is into riorly flanged at one end to a given diameter and at the opposite end is interiorly flanged to the same diameter and also exteriorly to determine the in to bushing, the e.

flange being adapted to fit within the recessed end of .the bushin, it being understood that the Fl. 1 is a partial smtion and elevation of a it with a pipefitted therein in the usual mer.

Fig. 2 is a section on line 2-2, Fi 1. by d is apartial tion and evation position of the lineril ends of the liner. are of;

of a bushing fitted with a liner of one p1 cylindrical and a portion of the outer. surface thereof is screw threaded at 11 to receive the cap or nut 12 forming the complementary member of the bushing as indicated at dotted lines in Fig. 1. The open ingin the bushing is of. a predetermined diameter andadapted to receive a-pipe 13 which is secured in position therein by a filling 14: of solder or other similar material placed within the recessed outer end 15 of the bushing. and the adjacent outer surface of the p till i e. a The liner made in accordance with my present invention comprises a body portion a 16' which is cylindrical and adapted to'fit Within the opening in the bushing. That is to say, the outer diameter of the body por-. tion 'of'the liner is substantially the same as the diameter of the opening, in the bushing. At one end the body portion of the liner is interiorly flanged as indicated at 17. As

curved inwardly to a predetermined extent so that the opening therein-is of thef'desired diameter. At the other end ofthe body or,

illustrated, this end of the lineris similarly tion pi the liner the same is flan; interlorly and exteriorly. The interior flange-is indicated M318 and curved toward the'inwardly curved flange 17 at'the opposite end oftheliner, while the outward or exteriorportion oi the flan e is indicated at 19 and is substantially at n ht angles to the bod portion at the liner. '1 e diameter of the I an 18 is the se as that of the flange 17 and the diameter oi the exterior ortioh 19, of the flange atthe outer end of t e liner may be greater t the outer diameter of the body liner to any desired ent.

illustratedin' Fig. 3, the a at the flanges 17 and 18 are substantially the same as that of the pipe21. In the use of the liner the same is plawd in the bushing so that the exteriorflange l9 abuts portion of the is preferably lit againstthe inclined surface at the recessed 1W portion otthe bushing, and thepipe .21 out smaller dieter than the diameter cit the bushing is fitted to position, engaged by the flanges 17 and 18 and then the parts secured together by the solder filling or fillin of other material in..the usual manner; In ig. 4, the liner as indicated is similar in all respects to that" shown in Fig. 3 with the exception that the interior flanges 17 and 18 are larger and consequently the diameters of the same are smaller than those of the corresponding parts of the liner shown in Fig. 3. Furthermore the construction of the liner is clearly illustrated in Fig. 5. It will be apparent, however, that the liner and its flanges may be made as an integralstructure, or either one or both of the flanges may be madeseparately'and suitably connected to the body-portion of the liner without departing from the nature and spirit of the invention,

' It will now be apparent that with the same size or standard bushing two or more pipes having diflerent diameters may be employed with a bushing having an opening of a predetermined diameter. For example, as shown in Fig. 1, if the pipe to be used has the same diameter as that of the bushing no liner is necessary; or if a smaller sized pipe is to be used, as indicated in Fig. 3, the liner having flanges of predetermined diameters corresponding with that of the pipe is first inserted in the bushing, the pipe placed in position and the arts connected; or as shown in Fig. 4, a iner havin g' flanges with-still smaller diameters may be employed for a pipe having a correspondinner surface of the bushing and having inturned portions in spaced positions, with the edges of the inturned portions adapted to engage the surfaceof a pipe passing into the liner.

2. A liner for a pipe bushing comprising a body member adapted to fit within the opening in the bushing and having inturned portions at the ends thereof, the edges of the said inturned portions being adapted to engage the surface of a pipe passed into the liner, and an outturned portion at one end of the liner adapted to engage the bushing to determine the position of the liner in the bushing.

3. A liner for a pipe bushing comprising a body portion adapted to fit the opening in the bushing and having an inwardly curved flange at one end thereof, and an inwardly curved and an outwardly straight flange at the other end thereof.

4. A liner for-a pipe bushing comprising a body member adapted to fit within the opening in the bushing, internal flanges at the opposite ends of the liner, the edges of theinternal flanges being adapted to engage the surface of a pipe passing into the liner. and an external flange at one end of the liner adapted to engage the bushing to determine the position of the liner within the bushing.

5. A liner for a pipe bushing comprising a body portion adapted to fit within the opening in the bushing, an internal flange of predetermined diameter at one end of the liner, an internal flange 0f the same diameter at the opposite end of the liner, and an external flange at one end of the liner adapted to contact with the surface of an internal recess in the bushing to determine the position of the liner in the bushing.
